STS-53 was a Space Shuttle Discovery mission in support of the United States Department of Defense. The mission was launched on 2 December 1992 from Kennedy Space Center, Florida.
Discovery carried a classified primary payload for the United States Department of Defense, two unclassified secondary payloads and nine unclassified middeck experiments.
Discovery's primary payload, USA-89 NSSDC ID 1992-086B is also known as "DoD-1", and was the shuttle's last major payload for the Department of Defense. The satellite was the third launch of a Satellite Data System-2 military communications satellite, after USA-40 on STS-28 and STS-38's deployment of USA-67.
Secondary payloads contained in or attached to Get Away Special (GAS) hardware in the cargo bay included the Orbital Debris Radar Calibration Spheres (ODERACS) and the combined Shuttle Glow Experiment/Cryogenic Heat Pipe Experiment (GCP).
